The Pharrell x adidas NMD Hu Trail 'China Exclusive' pack consists of four colorways, each symbolizing a natural element. Inspired by fire, the 'Passion' model features a red-dyed Primeknit upper with a Footwear White TPU cage and matching inserts overlaying the Boost midsole. The word 'PASSION' is embroidered in white on the upper right shoe, while the equivalent in Chinese characters adorns the left shoe. It released in May 2018 alongside ‘Peace’, 'Youth' and 'Happy' colorways.
